Problems solved by technology

2D resin is a methylol-based finishing agent. Although it can provide excellent anti-wrinkle performance, 2D resin-finished fabrics release formaldehyde during finishing, storage and wearing, which will cause great harm to textile producers and users.
Sucrose tastes sweet and is an important food and sweet condiment, but it has not been applied to the field of anti-wrinkle of cotton fabrics

Embodiment 1

[0030] It is known that the breaking strength of the pure cotton plain weave before finishing is 593.6N, the wrinkle recovery angle is 144.84° and the Hunter whiteness is 93.87.

[0031] (1) The preparation process of the anti-wrinkle finishing solution: prepare the reaction solution with sucrose and sodium periodate at a molar ratio of 1:3, the mass fraction of sucrose is 5%, the reaction solution is reacted at 20°C for 26h, and then added with periodic acid BaCl with a sodium molar ratio of 1:2 2 , after stirring for 1 h, filtered, and the resulting clear solution was mixed with MgCl 2 , JFC, and polyethylene softener are mixed to obtain formaldehyde anti-wrinkle finishing solution, in which MgCl 2 Concentration is 20g / L, JFC is 2g / L, polyethylene softener is 2g / L, mixed liquid pH=3.

[0032] (2) Anti-wrinkle finishing process: After the bleached cotton cloth is dipped and mixed with the finishing solution, it is dipped twice and rolled twice to control the liquid-carrying...

Abstract

A preparing method and application of a formaldehyde-free anti-crease finishing agent used for cotton textiles are disclosed, belonging to the field of iron-free finishing. The finishing agent is prepared by oxidizing a cane sugar raw material which is cheap and rich in source with sodium periodate, and adding magnesium chloride having a catalytic effect, a nontoxic softener and a penetrant, witha cane sugar aldehyde derivative being adopted as an anti-crease finishing agent. The disclosed finishing agent is used for anti-crease finishing of cotton textiles, ensures anti-crease effects, improves problems that strength loss and wear resistance loss are high in conventional anti-crease finishing, and allows textiles to be free of yellowing. As the cane sugar aldehyde derivative is formaldehyde-free, the finishing agent is green and ensures safety of the finished textiles from the source. The finishing agent is simple and reliable in process and meets requirements on green dyeing and finishing.

Description

technical field [0001] The invention belongs to the field of non-ironing finishing, in particular to a preparation method and application of a formaldehyde-free anti-wrinkle finishing agent for cotton fabrics. Background technique [0002] Pure cotton fabric has excellent wearing properties, and is currently an ideal fabric for clothing and home textiles, and is widely welcomed because of its good comfort. However, cotton fiber has poor elasticity and is easy to wrinkle, especially after washing, which affects the appearance. It is difficult to meet the various needs of modern people who pursue a healthy, comfortable, convenient and fast life. [0003] Non-ironing and anti-wrinkle finishing of cotton fabrics has emerged at the historic moment. At present, mature 2D resin non-ironing anti-wrinkle finishing technology and polycarboxylic acid finishing technology have been formed, which can make fabrics have a good appearance. 2D resin is a methylol-based finishing agent. Alth...
